, the same.

My invention has for its object to provide an apparatus for trimming the edges of soles, shanks, and heels of boots and shoes which shall be simple in construction and effective and cleanly in operation, the waste material being removed from the cutterand discharged at a distance. It may be described as consisting,-broadly, in'making the shaft on which the cutting-knife proper is set hollow, so that the.

portions shaved off from the heel, sole, or shank will fall into the shaft and be delivered at any point desired.

For full comprehension of theinvention reference must be had to the annexed drawings, in which Figure 1 is a longitudinal sectional elevation taken through center of shaft; Fig. 2, an end view of machine; Fig.3, a transverse section on line 00 m, Fig. 4, of knife; and Fig. 4, a modification of theconstruc'tion'.

Similar letters of reference indicate like parts.

A is the frame of the machine, preferably of some such form as that shown, in which are formed bearings for the shalt 13, having mounted on it pulley B, rotated by any suitable power.

O is the knife proper, made, as shown, inthe shape of a tube, with cutting-edges formed tangentially in the periphery,the section of the knife being'varied to suite. bevel or a straight out and properly shaped for a sole,

shank, or heel.

D is thesole-guard, secured in a socket, D,

pivoted to the frame, and provided with a spring, d.

E is the welt-guard, formed of a recessed plate, into which the knife enters slightly, secured to an arm, E, pivoted to the frame, and fastened by a set-screw, E.

Any number of cutting-edges or slots may be used, from one upward, and it will be seen that the action of the knife resembles closely that of a planer.

In some cases the shaftB maybe made solid and the knife 0 secured to the end of it and mounted on or made in one with a tube, F, projecting, as shown in Fig. 4, toward the front, into which the chips will fall and at the end of which they will be delivered.

,Suitable means will be provided by which the chips can be taken from either end of the shaft. into proper receptacles.

Having thus described myrinvention, I beg to state that what I claim is as follows:

1. In an edge-trimming machine, the hereindescribed combination, with a tubular knife, of a hollow shaft carrying same, substantially as set forth.

2. The combination, in an edge-trimmer, of a tubular knife with open cutting-edges and a hollow shaft on which it is mounted, all substantially as described.

3. The combination, with the shaft B, carried in the frame and suitably rotated, of knife 0, sole'guard D, and welt guard E, both secured to the frame, all as and for the purposes set forth.

4. The combination, in an edge-trimmer, of
